NSS has long traditions all the way back to the 60ties. Through the years the event was arranged at Bolkesjø Hotel and the symposium was so associated with the hotel that it also was named the “Bolkesjøsymposium”. The symposium was mainly driven by Norwegian Broadcasting (NRK) and Seem Audio. During the later events the program committee also got valuable support from Gerhard Stoll (IRT) and Florian Camerer (ORT). A lot of great audio engineers and speakers both from nordic countries and from abroad have participated at the symposium and the event has a strong branding and reputation in audio environments especially in Europe.
